Specification of Letters Patent.

Patented Sept. 17, 1918.

Y Application filed July 14, 1917. Serial No, 180,493.

To all w/toiit t may concern.'

Be it known that l, YKoL-A NAJKALYK, a subject of the King of England, resident of Myrnain, Province ol Alberta, and Dominion of Canada, have invented certain new and useful Improvements in Railroad- Joints, of which the following is a specification.

rllhis invention relates to iinpreven'ients in rail connections, whereby the ends of adjacent rails may be rigidly engaged together so as to be prevented trom movement, either longitudinally, vertically, or laterally.

One of the principal objects oit the invention is to provide ineans whereby rails inay be engaged in the manner stated without the use of fish or joint plates of any kind, and also to dispense with the use et bolts or like securing means.

' This object is accomplished by the novel design, construction and combination of parts hereafter described. and shown in the accompanying drawings, forming a material Vpart of this disclosure, and in which Figure 1 is side elevational view of a pair o1c abutting' rails, the ends of which are 'formed in accordance with the invention.

VFig: 2 is a transverse sectional view taken on line 2 2 of Fig. 1.

Fig. 3 is another' transverse sectional view taken on line 3 3 of Fig. 1, the parts prior to adjusting being shown in dotted lines.

Fig. 4 is a side elevational view of the end otan abutting rail formed in accordance with the invention.

Fig. 5 is a vertical sectional view through the end ot' the adjoining rail, and

l? G is a front elevational view of the rail shown in Fig. 4.

' ln the drawings, the heads of both rails are indicated by the numeral 10, the base 11 and stem 12.

The abutting ends oit both rails are of a thickness corresponding with the head of the rail, the adjacent portion 14C ot' one being recessed at 15, the horizontal overhanging part having a curved surface 1G, from which extends a cylindrical stein or rod having `formed upon opposite sides projections, respectively 19 and 20, while the abutting rail has an enlargement 2li and an extending element 25, formed with a recess 26, adapted to engage with the curved extension 16, the latter acting in the manner of a key and preventing lateral dislocation.

A cylindrical opening Q8 is formed axially in the rail end 2li and is provided with slot 29 through which the projections 19 and 2O may pass as the rails are pressed endwise together; when the projections have entered the transverse passages 30 and 32, the rails may be rotated one with respect to another, thus causing the projections 19 and 20 lo engage within the recesses, thereby locking the tivo rails positively together.

As the stem 1S is receivable within the persing QS. it holds the rails together so that one cannot n'iove relatively to the other, either up or down or side-wise., while the projections 19 and 20 entering the passages Si() and Si?, prevent the rails 'from being separated longitudinally,

Having thus described niy invention, what l cla-iin as new,and desire to secure by Letters Patent, is

1. r[he combination with a pair of abutting rails, of fixed lateral extensions at the ends thereof, a projection 'formed with the upper p 't oi3 one oit said rails, said projection ln ng a convex lower surface, a corresponding recess 'formed in the lower part oi the other rail, cylindrical stein extending troni said projection adapted to enter an axial opening formed in the other rail, and oppositely disposed integral keys formed on said stem adapted to engage with corresponding recesses formed in the abutting rail, said stem being semi-rotatable within the mentioned axial opening.

2. ln a rail oint connection, the combinan tion with a pair oit abuttii'ig rails, provided with end extensions, one of said extensions having a concave upper face and the other a convex lower face adapted to cooperatively engage a cylindrical stein extending irorn one ot' said rails adapted to enter an axial bore in the other rail, and lateral projections vtorined with said stein, whereby rotating one of said rails relative to the other causes the engagement of said projections in corresponding cavitics formed in the other rail.

In testimony whereof I have aflixed my signature.

NYKOLA. NAJKALYK.
